Seismic Response and Failure Mechanisms of Articulated Pile–Structure Systems in Liquefiable Soils: Insights from Shaking-Table Experiments and Numerical Analysis
Introduction Liquefaction is a critical concern for pile foundations supporting bridges, high-rise buildings, and offshore structures. In saturated sands subjected to strong earthquake shaking, loss of soil strength can induce large pore-water pressures, leading to reduced bearing capacity and excessive deformations. While numerous studies have documented macroscopic liquefaction phenomena, the dynamic interaction within soil–pile–structure systems,…

Numerical Analysis on Seismic Response and Failure Mechanism of Articulated Pile−Structure System in a Liquefiable Site from Shaking-Table Experiments
Introduction and Context Pile foundations are widely used to support critical infrastructure such as bridges, tall buildings, and offshore structures due to their robust load-bearing performance and adaptability to complex ground conditions. In liquefiable sites, earthquake-induced soil liquefaction can severely undermine pile behavior, leading to reduced bearing capacity, excessive deformation, and potential structural collapse. While…

Numerical Insight into Seismic Performance of Articulated Pile-Structure Systems in Liquefiable Soils
Overview: The Challenge of Liquefaction-Influenced Pile Systems In many geotechnical settings, piles anchor bridges, tall buildings, and offshore platforms. When saturated sands undergo liquefaction during an earthquake, the dynamic interaction between soil, piles, and superstructures can drastically alter bearing capacity and deformation patterns. This study, a collaboration between the Department of Hydraulic Engineering at Tsinghua…
